On a commercial scale, brewing is sometimes called "yeast farming". Commercial brewers are continually monitoring their yeast, brewing batches to keep their yeast samples viable, and refresh their yeast bank. On a homebrew scale it is easy enough to buy new yeast, but it is possible to manage your inventory to save that expense. That was the genesis of this brew.
The
1272 American Ale II yeast in my yeast bank was harvested last March. At best ten percent of the cells in the jar are viable. I loved what the yeast contributed to
Camp Randall Red IPA and the
Blueberry Wheat kit that I brewed. I want to re-brew Camp Randall Red and potentially use 1272 in another batch, but it will take some work to step up the number of yeast cells to even brew a two or three gallon batch.

Practicing getting the stir bar to spin. |
A
stir plate spins liquid via a spinning magnet, which causes another magnet inside of the flask called a stir bar to also spin, causing the liquid in the flask to stir. The stir bar is roughly the size of a pill. They are small and very easy to lose. I have managed to lose three of them already. The next time I buy ingredients I will buy a new one and a backup, but in the meantime I have to do without.
